This rotatable supporting means permits the razor blade to present its edges in cooperative relation to the guard and sharpening device and permits rotative movement of the blade to move the opposite faces of the edges of the blade for cooperation with the guard and sharpening device.

The base 35 of the U-shaped member 34 is slightly enlarged transversely and is provided centrally with a rectangularhole at 36, as shown in Fig. 7, tted to a squared end portion 37 of a plunger 38 which extends through the handle 39 on which the razor head l2 is rigidly mounted. The plunger 38 is provided adjacent to the squared end portion 37 with xed collars 40 and 4l securing the U-shaped member 34 'on the end of the plunger 38.

For the purpose of aligning the razor blade supporting means with the guard 13 and the sharpening roller 22, the arms 32 and 33 of the member 34 may be provided with studs 42 and 43 which cooperate with slots 44 and 45 in the end walls 16 and 17 of the razor head 12 so that when the razor blade is moved into the position shown in Fig. 2 the edges of the razor blade will be rmly retained in proper relationship with the guard 13 and the sharpening roller 22.

For the purpose of holding the razor blade in the position shown in Fig. 2, and also to permit its supporting and clamping means to be moved outwardly and away from the guard and roller so that it may be turned about its longitudinal axis or bodily about an axis perpendicular thereto to reverse the relation of the blade edge surfaces with respect to the guard and sharpening roller, I provide a spring 46 bearing against a shoulder 47 on the interior of the handle 39 and against a manipulative member 48 carried by the plunger 38. The manipulative portion may be threaded or otherwise engaged with the lower end of the plunger 38 to permit easy assembling or separatio-n of the parts.

As shown in Fig. 2 the razor handle 39 may be provided with an enlargement or collar at 50 formed separately and secured thereto in any desired manner, or which may, if desired, be integral with the handle, the outer edges of the same being preferably milled so that the collar may be held securely during the various operations in using the razor.

The manipulative portion 48 is preferably provided with a somewhat spherical end face and a knurled enlargement as shown, and preferably includes a cylindrical external skirt portion 51 which surrounds and is slidable on the handle 39. By means of this construction, as is apparent from Fig. 3, the index finger and middle nger of one hand may be placed on the collar 50 and the thumb of the same hand may be placed on the rounded end of the manipulative portion 48 to move the plunger upwardly and to raise the razor blade 14 out of cooperative relation with the guard and roller, and into a position in which the razor blade is free to be turned about the axis of the plunger 38. After the razor blade has been moved into this position it may be turned also about its longitudinal axis, or the razor blade together with the U-shaped member 34 and the stem 38 may be rotated by grasping the skirt portion 51 of the-manipulative member 48 between the thumb and index nger of the other hand, the skirt portion 51 being preferably provided with ribs to facilitate rotative movement. The razor blade may thus be turned edge for edge, ,or into the position shown in Fig. 3 in which position the parts may be readily cleaned.

When the razor blade has been moved into the position shown in Fig. 3, pressure may be removed from the manipulative portion 48 in which case the spring 46 will draw the U-shaped member 34 into contact with the roller 22. For the purpose of preventing accidental rotation of the razor blade out of the position shown in Figs. 3, 4 and 6, two curved portions 52 and 53 may be formed in the base 35 of the member 34 shaped to fit the roller 22. It is evident from Fig. 3 that regardless of the direction in which the plunger 38 and razor blade 14 are turned they will be held in position as indicated in Fig. 3 by the roller 22 and the cooperating portion 52 or 53.

It will be apparent that the box-like construction of the head piece l0 will serve to rigidly support the guard and sharpening roller in proper relationship to the blade, and the walls of the box-like enclosure may be made of relatively thin light weight material and still possess sufficient rigidity to prevent the razor parts from being bent out of proper relationship. It will be noted that in the ordinary use of the razor and the removal of the blade or during insertion Yof a new blade, it will be merely necessary to release the clamping member 26 by turning the thumb screw 28. The construction of the restricted neck portion of: the thumb screw 28 is such that this screw will always remain attached to the clamping plate 26. Accordingly even when the blade is being replaced, the entire razor construction and sharpening device will be constituted of but two parts and accordingly the likelihood of any of the parts being mislaid is obviated. During the replacing of the blade, if the parts are kept in the position shown in Fig. 1, the blade clamping members will be relatively rigidly held in position so that the thumb screw 23 may be readily manipulated without danger to the user. Furthermore, as indicated in Fig. 3 and as above explained, the relative positions of the two blade edges may be reversed while the fingers of both hands are kept in Contact with the handle in positions relatively remote from the blade and therefore during the actual use of the razor for shaving, if the blade edge in use becomes dulled somewhat, the user may immediately shift the other blade edge into position without any danger of the parts slipping out of the hands or of the blade edges coming into Contact with the lingers.

1t will be further noted that the construction Of the blade with slots at its ends, contributes substantially to the compact relationship of the parts in that the slotted blade areas provide space for the bearing screws 30 and 31 and their supporting lugs so that such parts need not protrude beyond the outer limits of the adjacent parts of the device.

While the invention has been described in detail with respect to a preferred example thereof which gives satisfactory results, it will be understood by those skilled in the art after understanding the invention, that various changes and modiiications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appended claims to cover all such changes and modifications.
